In this lesson, students will investigate the Doppler Effect and discover how the same principle can be used to identify a possible tornado in storm clouds and investigate the rotation of distant galaxies. Students should be familiar with the...(View More) electromagnetic spectrum and the concept of Doppler Shift (links to background information are provided). Materials required for every group of 2-4 students include: a Slinky toy, safety glasses, meter stick, and colored pencils. This lesson is part of the Cosmic Times teachers guide and is intended to be used in conjunction with the 1965 Cosmic Times Poster.(View Less)

This is a lesson about magnetism in solar flares. Learners will map magnetic fields around bar magnets and investigate how this configuration relates to magnetic fields of sunspots. This activity requires compasses, bar magnets, and a equipment for...(View More) the instructor to project a PowerPoint or pdf lecture presentation. This is Activity 1 in the Exploring Magnetism in Solar Flares teachers guide.(View Less)

In this activity, students demonstrate the relationship between wave frequency and energy in the electromagnetic spectrum by shaking a rope to identify the relationships. This activity is part of Unit 2 in the Space Based Astronomy guide that...(View More) contains background information, worksheets, assessments, extensions, and standards.(View Less)

In this activity, students study the range of colors in a visible light spectrum created from either a glass prism or holographic diffraction grating. This activity is in unit 2 of the "Space-Based Astronomy" guide that contains background...(View More) information, worksheets, assessment activities, extensions, and alignment to national education standards.(View Less)

Learners will build a spectroscope and use it to observe various types of lights. This activity requires spectroscope kits, diffraction gratings and fluorescent and incandescent light sources. The kits are available for purchase in packs of 25 from...(View More) Astronomers without Borders.
